I found a Bootstrap form on the internet and now I want to send it to my email. I have the form online, so no issues with localhost etc. When I try send it I get a message 'Thank You! I will be in touch'. So it sends? But I don't receive the email in my mailbox. Anyone an idea? See code below.
ps. When I run the code local he got some errors, see image. I don't have those errors online, but maybe that is the reason why it doesn't send anything?
<?php
 if (isset($_POST["submit"])) {
  $name = $_POST['name'];
  $email = $_POST['email'];
  $message = $_POST['message'];
  $human = intval($_POST['human']);
  $from = 'Demo Contact Form'; 
  $to = 'example@example.com'; 
  $subject = 'Message from Contact Demo ';
  
  $body ="From: $name\n E-Mail: $email\n Message:\n $message";
  // Check if name has been entered
  if (!$_POST['name']) {
   $errName = 'Please enter your name';
  }
  
  // Check if email has been entered and is valid
  if (!$_POST['email'] || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
   $errEmail = 'Please enter a valid email address';
  }
  
  //Check if message has been entered
  if (!$_POST['message']) {
   $errMessage = 'Please enter your message';
  }
  //Check if simple anti-bot test is correct
  if ($human !== 5) {
   $errHuman = 'Your anti-spam is incorrect';
  }
// If there are no errors, send the email
if (!$errName && !$errEmail && !$errMessage && !$errHuman) {
 if (mail ($to, $subject, $body, $from)) {
  $result='<div class="alert alert-success">Thank You! I will be in touch</div>';
 } else {
  $result='<div class="alert alert-danger">Sorry there was an error sending your message. Please try again later.</div>';
 }
}
 }
?>
